Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 283.16 g/mol gives 1-Bromo-5-phenylnaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-5-phenylnaphthalene (CAS 911836-38-9), molecular formula C16H11Br and molecular weight 283.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Bromo-5-phenylnaphthalene (C16H11Br) is characterized by bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-Bromo-5-phenylnaphthalene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
